Would you like your party to make better choices of candidates in the
primary elections? In particular – would you like it to choose the
best presidential
candidate it can?
Would you like to get rid of the "spoiler effect", where alternative (third
party) candidates on the same side of the political spectrum as you can take
votes away from your candidate and cause your candidate to lose?

Would you like to have more than two realistic choices of candidates to
choose from?
Would you like to vote for and show your support for alternative party
candidates, without having to waste your vote to do it?

Would you like to vote for and show your support for your favorite
candidate, but still have the option of supporting the Democrat or
Republican candidate, if your favorite is unlikely to win?
Would you like your opinions about every candidate to get used, as opposed
to just your opinion about one (and even that one
is wasted since it is a third-party candidate)?

Would you like the
alternative parties to eventually get stronger,
so that you could run as a candidate of
one of them if your party turns away from you or
you lose your primary – and then that run would both (1) have a realistic
chance of succeeding, and (2) would not lead to a vote split between
you and the opponent from your old major party, causing you both to lose – instead
one of you would still win and you would not be regarded as a "traitor" for
doing this?

Tired of pseudo-democracy
where you get the minimum possible amount of choice (two, but usually
really only one since there's 98% predictability)
and where you only get to express the minimum possible amount of information
about what you prefer?
Would you like more real choices and more expressiveness so it might
actually be worth bothering to vote?
We don't know about you, but we don't want the minimum.
We want the maximum.
